“He was obsessed — obsessed with fighting Nate Diaz again,” UFC President Dana White said in an interview with ESPN. “Obviously, [UFC CEO Lorenzo Fertitta] and I tried to argue with him and said, ‘Let’s go back to 145 and defend your title. Or if you really want the Diaz fight that bad, do it at 155.’ He wants the fight at 170.

“Even his coach tried to get him to get off the rematch and off the 170-pound fight,” White added. “But it’s what he wanted.”
